Printer suddenly turned off and not turning on

Recommended Posts

Hello guys,

I've got my printer jammed (wonder why, was printing as always) so I decided to detach the nozzle to clean it up. The problem was not in the nozzle, it was in that PEEK thing or something, because the filament didnt even reach the nozzle. So I decided to heat it and try to clean it with something (is that OK to heat with detatched nozzle?) and suddenly my printer turned off after reaching temperature around 180 degrees. Now its not turning off... Well, it TURNS on for less then a second, then shuts down, and it repeats this process over and over. I dont know what happened, but I guess its related to power supply. When I connected printer to pc, it turnes on normally, but now I get the maxtemp error. I tried reconnecting almost everything that was on board (not sure which cable is the power one). But my power supply's power button is shining even when I have it plugged off. Wonder if it is damaged?

Any suggestions, please?

I had this problem tonight. Not sure if your cause is the same, but for me, when I was re-assembling the heater block, the amount of force I put on the heater/thermocouple set screw was crushing the wires of the cartridge heater and causing an internal short. The breaker in the power supply would trigger every time I turned on the machine.

I was able to remove the heater, manually separate the wires at the 90degree bend, and delicately reinstall the heater, solving the problem.

Try removing your heater cartridge wires from the main board and turning on the machine - see if that's the problem. Remember to unplug your power supply first to reset the breaker.
